Abstract
The invention relates to a thermal cycle of power generating system. A current closed thermal cycle used in electric power stations requires both heat source and cooling source. The heat source temperature needs to be much higher than that of the cooling source. In order to raise the heat source temperature, electric power stations consume fuel, causing environmental pollution and fuel shortage.
The invention aims to solve the above-mentioned problems by using the thermal cycle only with heat source; without cooling source. The removal of the heat source temperature restriction enables the hear source temperature to go down to atmospheric temperature. This means that clean power can be generated from solar thermal energy and fuel is not necessary.
Description
- The invention relates to a thermal cycle of power generating system. A current closed thermal cycle used in electric power stations requires both heat source and cooling source. The heat source temperature needs to be much higher than that of the cooling source. In order to raise the heat source temperature, electric power stations consume fuel, causing environmental pollution and fuel shortage.
- The invention aims to solve the above-mentioned problems by using the closed cycle only with heat source; without cooling source. The removal of the heat source temperature restriction enables the hear source temperature to go down to atmospheric temperature. This means that power can be generated from solar thermal energy and fuel is not necessary.
- FIG. 1 is a typical system diagram of the invention. Each components in the diagram are as follows: 1: heat source ( solar thermal heat source), 2: turbine, 3: gas liquid separator, 4.: pump, 5: compressor, 6: gas liquid mixer, 7: electric generator, 8: rotation axis.
- FIG. 1 shows a typical system diagram of the invention.
- Working fluid flows through
heat source 1 intoturbine 2. Inturbine 2 thermal energy is converted to power, which rotates turbine axis. -
Compressor 5 andelectric generator 7 which are coupled toturbine 2 with rotation axis, are driven by turbine axial power. - At the outlet of
turbine 2 the fluid condenses 10 - 40 wt %, and is separated into gas and liquid in gas-liquid separator 3. - Liquid is pressurized by
pump 4. Gas is compressed incompressor 5. Liquid and gas are mixed in gas-liquid mixer 6. The fluid returns toheat source 1. Thus a closed cycle of working fluid is formed. - An example of calculation results for the system diagram is as follows.
working fluid nitrogen oxide (NO) turbine inlet conditions pressure 38 (bar), temperature 180 (K.) liquid phase weight percent 0% turbine outlet conditions pressure 0.5 (bar), temperature 108 (K.) liquid phase weight percent 25% electric generator output 7% of turbine axial power - At the outlet of
turbine 2 the fluid condenses 25 wt %, and as the gas reduces to 75% of total flow, the power consumption ofcompressor 5 decreases to less than turbine axial power. Consequently, electric generator output is produced. - As for the working fluid, saturation temperature of gas species has to be less than atmospheric temperature to produce power from atmospheric temperature heat source.
- Clean power is generated from naturally supplied solar thermal heat source producing no other influence than heat removal in the natural world.
